Beta Testing Orange Bridge

Getting Started

Orange Bridge is a web application supported by popular Internet browsers for mobile and desktop devices. You can test it here during our beta period. Orange Bridge utilizes Bitcoin and Ethereum Mainnet networks. This means that all transactions are mined on each blockchain network. During this beta, only bridges between the following blockchains are supported:

Bitcoin
Ethereum

The BRC20 inscription for ORNJ tokens is https://unisat.io/brc20/ornj

Once bridged, the ERC20 EVM token contract address for ORNJ is 0x2E8607dA39A40D780406dCf1207B9C27221137Fc All bridged transactions and Bridged TVL (Max Total Supply) between the Bitcoin and Ethereum blockchains for ORNJ can be located here: https://etherscan.io/token/0x2e8607da39a40d780406dcf1207b9c27221137fc

Please note that Orange Bridge is in beta and an experimental phase. While contracts have been deployed on Mainnet, have undergone quality assurance testing, and are undergoing a security audit, there is always a risk of errors that may result in a loss of funds. We encourage all tests to be conducted with a small amount of funds. Due to the associated risks, Orange Labs accepts limited liability during this testing phase.

Connect Wallets

Enabling Mainnet on Your Wallet

To use Orange Bridge, you must connect your Bitcoin and Ethereum wallets, which contain the assets you would like to bridge and receive the bridged assets. Connecting both wallets ensures your security, minimizes the risk of error, and provides the most straightforward user experience for bridging assets.

Please ensure that you are logged in to both wallets and that both wallets have your accounts logged in.
Both wallets should be on the Mainnet network. For the Orange Wallet, check the Network Indicator if you are on Mainnet. If you are on Testnet, change networks by:
1. Navigate to the top-right gear icon and tap Settings
2. Tap Network
3. Tap Mainnet
4. Tap Save

For Metamask, check the Network Indicator if you are on Mainnet. If you are on Testnet, change networks by:

Navigating to the top-left network drop-down and tap the network selector
Tap and select Ethereum Mainnet
After the setup of the wallets, return to Orange Bridge and tap the Connect BTC and Connect EVM buttons to connect your wallets:

Connecting the Orange Wallet
